Energy-efficiency is the main concern in most
Wireless Sensor Network (WSN) applications. For this purpose,
current WSN MAC (Medium Access Control) protocols use duty-cycling
schemes, where they consciously switch a ...

The challenging problem of time synchronization in wireless sensor networks is considered in this paper, where a new distributed protocol is proposed for both local and multi-hop synchronization. The receiver-to-receiver ...

Duty-Cycle at the MAC layer plays a key role in energy savings and network lifetime extension. It consists
in putting a node’s radio in the sleep state as soon as it has no communication activity. Traditional WSN
MAC ...

Optimizing energy consumption and end-to-end (e2e) packet delay in energy-constrained, delay-sensitive wireless sensor networks is a conflicting multi-objective optimization problem. We investigate the problem from a game ...
